AUxiLIARY oR EMERGENCY sAFE'iiYsUPEoRT EoR BRAKE BEAMS.

Application rled Februaryl ,19, 1925. Serial No. 7,756.`

To all 'zo/wm it may concern.' Be it known that we, VILLIAMl W. CLoUsER, a citizen of the United States, and a resident of Hackensack, in the county of Bergen and State of New Jersey, `and CHARLES R. Busen, a citizenv ofthe United States, and a resident ofEast Orangein .the county Vof Essex and State of NewrJerl sey, have jointly invented certain new and useful Improvements in Auxiliary 0r Emergency Safety Supports for Brake Beams, of which the following is a. specification;

The invention pertains to railway brake beams, andv particularly to novel auxiliary or emergency supporting bars extending below-and toreceive the brake beams inl the event that said bea'mslshould become detached from their hangings, one purpose'of the invention .being to prevent, in case 'of accident, .the brake beams from falling under the wheels, derailrnent being thus avoided.

A further object of the invention resides in the means we have uprovided yfor securing the auxiliary or vemergency supporting bars against the bottom of the vspring plank,

ends of thehangers and against the bottom '7 of the spring plank, while eiiicientlysecuring the bars in position, permit of the convenient detachment of the same from vthev spring plank. Our invention` alsoy involves means for preventing endvvise movement or transverse movement of the auxiliary or emergency supporting bars, 'these Vmeans also preventing, in connection with they auxy, iliary bars, any lateral creeping of the aforet "offspring plank-'and 16- portions of inside- `hung trussed brake beams of usual character, fthe be'ai'n-parts shown being the voomfrom the detailed'` description hereinafter the section presented, lreference being had to the vaccompanying drawings, in which:

Fig. 1 is a vertical longitudinal section,

partly, broken away, through a car truck v'through "t-he'sameftaken on the dotted line of of Fig.` 2;

Fig. 5 is a fragmentary vertical longitudinal sectionthrough `the central portion'of one of the auxiliary .or safety bars;

.' Fig. 6 is a side elevation, partly brokenr away and partly section, of a modified embodiment of our invention, Fig. 6 corresponding lwith'Fig.v 1, but illustrating the employment of longer hangers thanthose v'shown in Fig..1 and an auxiliary safety bar having depressed portions forthe accommodation of brake beams which may hang below the lower horizontal plane of the spring plank;v

'7 `is a likel section througha further modified formv ofthe invention, this section showingthe'applioation of the invention to f aA different typeof spring plank;

f -Fig. 8"is-a section on the line 8-8 of Fig. 9,'of a further modified form'of theinvention, this modification consisting in having the hangers integral with a bridge-piece extending across theupperl surface of the Aspring' plank, kwhich in this instance has edge kflangeswhich are ltoo shallowv to safely take .the vhangers without said bridge-piece being Present;

'f Fig. 9 isv a topview of'the construction shown 'in `FigQAS, and

inclusive,"f15 designates a conventional form In the drawings, referring to Figs. 1 to 5 y Cil pression members 17 and truss rods or tension members 18.

lVith reference to Figs. 1 to 5 inclusive, we would say that the inventionresides in the auxiliary or emergency safety -bar 19 and the means for securing this bar in a detachable manner to the spring plank 15, said means comprising hangers 20, 21 of wrought metal extending downwardly from the upper edges of the side flanges of the spring plank 15, and said hangers being of special construction adapted to the securing of the bar 19. y

There will be a bar 19 and hangers 20, 21 at each side of the car truck, and said bars extend longitudinally below the end portions of the brake beams and are adapted to receive said beams in the event of accident to the brake beam hangers or other parts whereby said beams should become detached and fall.

In the present instance the auxiliary bars 19 are of inverted channel shape and are formed with a longitudinal depression, as at 22, along the center of their upper wall, this form of bar possessing great strength without undue use of metal and without occupying undue space in the means by which the bars are supported. In the construction shown in Figs. 1 to 5 inclusive the bars are plain straight channel bars having the longitudinal depression 22 and at the center thereof being pressed upwardly, as at 23, to form a fiat section for a rivet 24, this rivet 24 being carried by the bar 19 and having an enlarged upper end portion 25 which lits within a vertical aperture or opening 26 formed, by burning or otherwise, in the transverse central portion of the. spring plank 15. The rivet 24 is detachable from' the spring plank, but when in the position shown in Figs. 1 and 2, said rivet serves to center or key the bar 19 against endwise movement and also against lateral movement.

The hangers 20, 21 are alike, except that they are reversed when in position on the spring plank, and said hangers each comprises a broad vertical body-portion 27 which is of hook formation along itsupper edge, as at 28, to be hooked upon the upper edge of the side iiange 29 of the spring plank, the body of the hanger lying against the outer vertical side of said flange and extending downwardly below the spring plank. The hangers 20, 21 are each formed of sheet metal initially of rectangular outline, and this blank of metal is formed at one edge with the hook 23 and at its other end is split or bifurcated, and the portionsat opposite sides of the split or bifurcation are twisted outwardly in reverse directions to form the corresponding ears 30 at the lower end of each hanger, the space between the ears 30 of each hanger being such as to snugly re ceive the width of the bar 19, as shown in Figs. 3 and 4.

The ears 30 are, of course, integral with the body portion 27 of the hangers 20, 21, as shown in Figs. 3 and 4, and said ears are formed with corresponding transverse openings 31 to receive locking pins 32 by means lof which the bars 19 are firmly secured in position against the bottom of the spring plank, as will be understood on reference to Figs. 3 and 4. The openings 31 in the ears 30 are reinforced by embossing the metal around said openings outwardly, as at 33, the embossments 33 serving not only to strengthen the ears 30 but also to afford longer bearing surfaces at openings 31 for the pins 32. Each hanger 20, 21 is in one integral piece of wrought metal, and hence is not only of simplified construction but of great strength and durability.

When it is desired to apply the auxiliary or emergency bar 19 to the spring plank, said bar may be given the position in which it is shown in Fig. 1 with the upper enlarged 'end of the rivet 24 applied within the opening or hole 26 in the spring plank, and thereupon the hangers 20, 21 may be hung upon the spring plank with their ears 30 straddling the bar 19, after which the pins 32 may be driven through the openings 31 in the ears 30 for securing said bar 19 in lirm engagement with the bottom of the spring plank, the application of said pins 32 to position also serving to act downwardly against the hangers 20, 21 and increasing the gripping action of the hooks 28 against the lianges of the spring plank. The pins 32 are tapered at one end and have a head 34 at the other end, and said pins are in the nature of wedge pins and are driven through the'v openings 31 in the ears 30 with wedging or binding effect against the iianges of the bar 19, the forward end of said pins being tapered, as at 35, to enable them to enter the apertures 31 in the far ears 30 and to impinge strongly against theV iianges of the bar 19. The binding action of the pins 32 against the flanges of the bar 19 may be emphasized when the pins 32 have the tapered forward ends enabling them to find their path through the apertures in the far ears 30. The lower edges of the bar 19 are pref erably recessed inwardly, as at 36 (Figs. 3, 4 and 10), to form transverse concave seats for the pins 32, these seats serving as recesses and interlocking with the pins 32 and, while affording substantial bearings for the pins 32, also preventing the bars 19 from having endwise movement. rlhe recesses 3G are formed by pressing the lower edges of the sides of the bar 19 inwardly toward each other at the points where said sides are to be engaged by the pins 32, as will be readily understood on reference to Figs. 3, 4 and 10.

After the bar' 19 and `hangers 20, 21 have been applied to the spring plank and said structure of our invention is one of great rigidity 'and' strength and is immovably held in place, the pins 32, 32 lpreventing endwise movement of the bar 19 and the,

rivet 24 preventing lateral movement inthe bar 19 and hangers 20, 21, said hangers Vmoved from the hangers 20, 21 and 'fro1n` the spring plank at any time it may seein to be desirableto detach the same, and in carrying out this feature of the operation it will be obvious that on thev removal of the pins 32 the bar 19 may bedropped di rectly downwardly from the hangers 20,21. The hangers 20,21 may at thatl time also be removed from the spring` plank, if it should be so. desired, bymerely lifting .the hangers from the flanges 29 ofthe spring plank. f i

The pins 32 are formed at their forward ends with holes to receive cotter keys, as shown in Figs. 3 and 4, and we kpreferably apply to each pin 32 a pin-lock 37 which will prevent the loss of the pin in the ab-.

sence of the cotter key whether Vby .reason of said key not having beenV supplied to the pin or having become broken or otherwise destroyed. The pin lock 37 is formed of sheet metal and has one member 38 against the outer side of one ear 30, a corresponding Vmember 39 against the outer face of the opposite ear 30, a member 40 connecting said members 38, 39fand an extension member 41 bent' over from the member39 against the-head'34 of the pin 32, said members 38, 39' being apertured to permit the lpin 32 to pass through them. We do not limit our invention to the employmenty of the: pin lock 37, but we are aware that itis of advantage to apply saidu pin lock Y to Veach vof the pins 32.l n l In-fFig. 6 we illustrate a construction of the auxiliary or emergency supporting bary hangers 58, 5,9 shown 1n Fig. 7 correspond and hangers adapted'to car'truck structures in which-the brake beams hanging lower than shown in Fig. 1, extend below the lowei` horizontal plane of the spring plank. In Fig. 6 we number the spring plank 15, sinceit is the same las the spring plank shown in Fig. 1, and we number the auxiliary or emer'gencysupporting bar 42 and .the hangers 43, 44,` respectively. Vhangers Vare formed o n `'their upperxends;

These with hooks 45 to engage the upper edges of the side flanges ofv thespring plank 15 and thence extend downwardly a consider@ able distance below the bottom of the'spring plank and are formed with ears 46 corresponding with the ears 30 shownV ink Figs.

1 to .4 inclusive. Thehangers 43,44 do not` require special detailed description, be-rv cause they differ from the hangers 20, 21 of Fig. 1 in being of vgreater vertical length than said hangers 20, 21. The auxiliary bar 42 is bent upwardly at its middle portion, as at 47, soas to engagethe bottom of the spring plank 15 and at the apex of its upwardly bent portion said bark42 is provided with a rivet 48 corresponding with the rivet 24 shown in Fig. 1, said rivet 48 having an enlarged upperrend portion 49 which freely fits within a vertical hole 50 formed in the spring plank. extends longitudinally of the-truck, one end portion being below one of the brake beams andV the other end portion being below the other'brakey beam. The bar 42 corresponds exactly with the bar 19 of Fig.Y 1 with the exception that tol meet the situation created by the VVlower-'hung brake beams, the end portions of said bar 42, by bending the bar itself, are positioned von va low horizontal plane to extend below and normally free of the brake beams.' In Fig. 6 the end portions of the bar are secured between the r pairs of ears 46 by'means of wedge-pins 51 corresponding exactly 4with thepi'ns 32 of Fig. 3, and preferably we apply upon the pins `51, pin-locks 37 of the kindshow-n in Fig. 3. i

In Fig. V7 is shown-a different'itype of'y spring plank having. angle-iron bars 52 at its front and back edges. lIn Fig. 7 the auxiliarybar is!l numbered 53 and corresponds with the Ybar 19 of Fig. l with'the exception that said bar 53' in itstop portion is flattened upwardly at tworpoints, as yat l54, to. engage the lower fiat' surfaces .ofthe rivetf24 shown in Fig. 1,'but owing to the type of the spring'fplank shown in Y' Fig. 7

it is necessary.' to employ Vtwo of the rivets 55, one to engageeach. angle bar 52. The

with` thehangers 20,21 shown in Fig. 1, said hangers 58, 59 Vhaving the laterally vturned ears 60 to receive Vthe auxiliary bar 53, lwhich is held in place by wedge pins 61 of the kind shown in Fig. 3. ``Prefer- `ablythe pins y61 will each be equippedwith a pin-lock 62 correspondingV with th'epin-l lock37 vvshown in Figs. 3 and 4.

, In Figs. Sand 9 we illustrate our invention asapplied to avery shallow well-known f form of spring plank 63, land in Figs. 3 and ,9,1 64 denotes the auxiliary emergency supporting bar and 65, 66 denote'the hangers formed of -plate metal suspended from the 'opposite flanges of said springplank andv having the vears r67 correspondingwith the ears 30 of Fig. l between: which thegbar 1 The bar 42 TheY rivets v55 correspond exactlyl with the, l

llO

64 is supported on pins 68 corresponding exactly with the pins 32 of Fig. 3. The pins 68 will also preferably be equipped with pin-locks 69 of the kind shown in Fig. 3. The hangers 65, 66 are in themselves substantially duplicates or1 the hangers shown in Figs. l to 4. inclusive, but in this instance owing to the shallow nature of the spring plank 63, we connect the hangers 65, 66 by an integral bridge-piece 70 which lies upon the upper surface of the bottom of the spring plank and carries a rivet 71 Whose enlarged lower end 72 snugly iits within a hole 78 formed in the spring plank 63. The bridge-piece and hangers 65, 66 are all formed out oit one integral plate ot metal, as will be fully und rstood on reference to Fig. '9. rlhe rivet 7l correctly positions the hangers on the spring plank and there holds them.

In all the forms of our invention we provide an eiiicient auxiliary or emergency supporting bar extending longitudinally below and free of the brake beams, and in all of the forms of our invention we provide special wrought metal broad plate hangers detachably applied upon the spring plank and having at their lower ends ears between which the auxiliary supporting bar is received and which are correspondingly transversely apertured to receive locking pins 32 which engage the bar and firmly bind the same against the bottom of the spring plank, and in each form of our invention, except that shown in Figs. 8 and 9, the auxiliary bar is provided with a rivet, stud or the like to engage an opening in the spring plank, whereby the bar is correctly positioned and centered and prevented from endwise or lateral movements and the hangers are held against lateral movement on the spring plank. In the form of the invention shown in Figs. 8 and 9 the aforesaid rivet, stud or the like is carried by the bridge-piece 70 and engages the springplank and serves to correctly position the hangers and hold them, and through them the bar Gil, against lateral movement on the spring plank.

Our invention admits oit modiiication to meet the requirements of the various spring plank structures, as the drawings indicate, and we desire to cov r all modiiications as may be within the spirit of the invention and the scope oi' the appended claims.
